<\/a><\/p>\nThe seat is made with 3\/4″ AC plywood and is held together with pocket screws.\u00a0 The cushions are 2″ foam with a 1\/4″ plywood back that is attached to the seat via some #10 screws that fit into T nuts that are epoxied into the cushion base.<\/p>\n The seat is designed to sit directly on the floor of the cockpit and will not adjust.<\/p>\n In real fighter aircraft, the seat only moves a limited amount up and down.\u00a0 Any adjustments fore and aft are actually done by moving the rudder pedal assembly instead of the seat.<\/p>\n The seat got the same primer as the cockpit and the finish paint is the light gray that was used on the lower cockpit area.<\/p>\n In order to get the instrument panel installed, a 1″x3\/4″x1\/16″ section of aluminum angle was installed to support the bottom edge of the panel:<\/p>\n In order to get the angle section to fit, the ends needed to be beveled at a 45 degree angle:<\/p>\n The brace material was purchased at Ace, so if you build one of these you can easily find the bracing material.<\/p>\n I had started working on the instrument panel bracing while I was waiting for the metal I’d ordered for the new throttle quadrant to arrive…\u00a0 Fortunately, buying from Online Metals has the advantage of fast shipping.\u00a0 They’re in Seattle so UPS ground is essentially next-day service for me. \ud83d\ude42<\/p>\n The throttle quadrant is a three lever control system (throttle, mixture and prop pitch) based on the throttle project in Mike Powell’s new book,\u00a0 Building Recreational Flight Simulators<\/a>.<\/p>\n I changed the design and part layout to accommodate the space requirements of my ‘109 cockpit.\u00a0 In order to make the lever system simpler to build, I needed to cut six .062 spacers to replace the multi-part assembly that made up the two “sides” of each control lever.<\/p>\n Cutting aluminum on my ShopBot can sometimes be a pain.\u00a0 I don’t do it very often and as such tend to misplace my speed and feed notes between times I do cut it.\u00a0 This usually ends up in at least one broken cutter and lots of cursing. \ud83d\ude42<\/p>\n The levers are cut from .125″ thick 6061 aluminum.\u00a0 Each lever has a different length because they need to be staggered in order to not interfere with the operation of the other levers in the quadrant.<\/p>\n The two shorter levers will be bent at the base of the narrow section.\u00a0 The middle lever is bent at 22.5 degrees and the right-most lever is bent at 45 degrees.<\/p>\n Next up is the knobs for the levers.\u00a0 This was an utter mess from the word go.\u00a0 I wanted to cut them from 1″ acrylic, but soon discovered that the only “proper” bit that I had for cutting acrylic (an “O” flute bit) only had a .875″ cutter length.\u00a0 I decided to try a 2 flute downshear cutter I had handy.\u00a0 Bad idea.\u00a0 The result was totally unusable.\u00a0 I ended up ordering a new 1 inch long, “O” flute cutter from Centurion Tools<\/a>.\u00a0 The end result was well worth the $21 that the cutter cost.<\/p>\n The end result is awesome!\u00a0 They look great mounted on the lever arms:<\/p>\n …and finally, this is what the quadrant looks like assembled:<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/a><\/p>\n<\/a><\/p>\n<\/a><\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
